Chevrolet's customer relations department wishes to estimate the number of days it takes an automobile dealer to sell a Chevrolet Aveo. Some cars are sampled to produce an estimate for the mean number of days for an Aveo to be sold. Which of the following ideas is false when calculating the estimate? O If the standard deviation is small, a wider estimate will be produced. O If the standard error is small, it will produce a narrow interval. O If the confidence level is high, it will produce a wider error term. O If the sample size is increased, a narrower confidence interval will result.
